relay is fully functional, the OUT5 output contact is closed. Since all output relays are disabled when a
relay trouble alarm exists, OUT5 opens when relay trouble occurs.
Table 6-16. Relay Trouble Alarms
I.D. # Name Description
1 RAM FAILURE Static RAM read/write error.
2 ROM FAILURE EPROM program memory checksum error.
3 UP FAILURE Microprocessor exception or self-test error.
4 EEPROM FATAL ERROR EEPROM read/write error.
5 ANALOG FAILURE Analog to digital converter error.
6 CALIBRATION ERR Relay not calibrated or calibration checksum error.
7 PWR SUPPLY ERR Power supply out of tolerance.
8 WATCHDOG FAILURE Microprocessor watchdog circuit timed out.
9 SET DEFLTS LOADED Relay using setting defaults.
10 CAL DFLTS LOADED Relay using calibration defaults.
Relay trouble alarms, except for CALIBRATION ERR, EEPROM FATAL ERR, SET DFLTS LOADED, and
CALDFLTS LOADED indicate that the relay is not functional and causes the self-test diagnostics to force
a microprocessor reset to try to correct the problem.
CALIBRATION ERR, EEPROM FATAL ERROR, or DFLTS LOADED errors indicate that the relay is
functional but needs re-calibration or the settings reprogrammed.
Any relay trouble alarm will disable the protection functions, light the Relay Trouble LED, and place the
output contacts in their normal, de-energized state. If a relay trouble (RA-REL) alarm is cleared by
pressing the HMI Reset key while viewing Screen 1.3 or using the RA=0 or RA-REL=0 commands, then
the relay will attempt to return back online by issuing a software reset. The relay resets by going through
a full startup and initialization cycle. If no problems are detected, the relay returns online and enables
protection.
Major, Minor, and Logic Programmable Alarms
The programmable alarms function covers all circuits monitored by the continuous self-test diagnostics
function that do not affect the relay core functions. Alarm functions used to monitor the power system and
equipment are also part of the programmable alarms. Table 6-17 provides a detailed list of all
programmable alarms. The programmable alarm points can be prioritized into Major and Minor alarms
using BESTCOMS. Major alarm points, when triggered, causes the HMI Major Alarm LED to light and the
BESTlogic variable ALMMAJ to assert. Minor alarm points, when triggered, causes the HMI Minor Alarm
LED to light and the BESTlogic variable ALMMIN to assert.
Any programmable alarm can also be used in programmable logic expressions without programming it to
be reported by the programmable alarm reporting function. The ALMLGC variable is provided for this
purpose. Programmable alarm variables can be masked to drive BESTlogic variable ALMLGC by using
the SA-LGC command.
